[Abstract]
Object To optimize the extraction conditions of Fumai Decoction. Methods Uniform design test was used, and the contents of glycyrrhizinic acid and ginsenoside Rb 1 in extracted solvent were determined by HPLC. Results The ethanol volume and the extracting temperature in the uniform test impacted the test remakably. The best extraction process of Fumai Decoction as follows: the raw drugs were extracted by 10 times of 50% ethanol at 60 ℃ for 4 hours. Conclusion Glycyrrhetinic acid and ginsenoside Rb1 contents in Fumai Decoction are higher according to the above extraction process.
